upgrade firmware McData Eclipse 2640

I've been trying to upgrade the firmware in a 2640 to version 5.3.0. Originally I was told that I needed to upgrade to bootrom version 1.0.5 first but when I try to do that it tells me that version of the bootrom does not match the current firmware. So I updated the firmware first. It only updates the firmware in the inactive bank. Then I activate the updated bank and reset the switch. When I log in to the upgraded firmware it tells me I need to update the bootrom. When I try to update the bootrom it tells me I'm trying to load invalid code. Either I was given the wrong file or it has been corrupt or something like that. Does anyone know where I can download the 1.0.5 bootrom code to make sure I've got the right file?

Sorry about the wrong forum. I wasn't sure which one to post it to. That is the filename I have and I am currently on 1.0.3 but it will not let me do the firmware first. It comes up with "Error: Attempting to download the wrong image to flash." I have tried on another switch that is still running the 4.7.0.SB firmware.
